SPECIFICATION forming part of Letters Patent No. 778,061, dated. December 20, 1904.

Application filed May 24, 1904. Serial No. 209,533.

T0 aZZ whom it may concern:

Be it known that I, ADOLPH MUELLERWEIss, a citizen of the United States, residing at Sebewaing, in the county of Huron and State-of Michigan, have invented new and useful Improvements in Patterns, of which the following is a specification.

My invention relates to new and useful improvements in patterns; and its object is to provide an adjustable device for laying off blanks for producing tubular objects having their opposite ends rectangular and round, respectively.

The device is especially adapted for use injustable ends, to which are connected flexible rods. Slides are adjustably mounted upon the arms, and interposed between these slides are rules which are pivoted together, one rule-being parallel at all times with the adjoining arm. A novel arrangement of connectinglinks are employed for imparting movement from the slides to the rules, and the arms are provided with graduations, whereby the pattern can be quickly adjusted to produce blanks of proper dimensions.

The invention also consists of the further novel construction and combination of parts hereinafter more fully described, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is a plan view of my improved pattern. Fig. 2 is asimilar View of a blank which may be produced by the pattern. Fig. 3 is an enlarged section through the wire-clamping block, and Fig. 4 is an enlarged transverse section through one of the arms and the slide therein.

Referring to the figures by numerals of reference, 1 and 2 are side arms having grooves 3 in their front faces, which are provided with a desired number of graduations 4, suitably designated by numerals. Mounted within the grooves 3 are slides 5 and 6, respectively, which are adapted to be secured in adjusted position by means of set-screws 7. End strips 8 are adjustably mounted upon the grooved arms 1 and 2 and maybe locked in adjusted positions by set-screws 9, and at the outer end of each of these strips is a tubular projection 10, in which is adjustably mounted one end of a wire 11. The two wires are adapted to cross and extend through 'a clamping-block 12, which is adj ustably connected to one end of a strip 13 by means of a screw 14. Slide 13 is adjust ably connected, by meansof a set-screw, with a central arm 16, having a groove 17 in its front face, in which is mounted a slide 18, similar to the slides 5 and 6. This arm is also graduated, said graduations being designated by suitable numerals, and a set-screw 19 is employed for locking the slide 18 in adjusted position. Pivoted to the slide 18 and extending in opposite directions there: from are rods 20 and 21. Rod 20 is pivot ally connected to one end of a ruler 22, and

1 rod 21 is connected in a similar manner to one end of a ruler 23. The other end of ruler 22 is pivoted to a ruler 24, while the other end of ruler 23 is pivoted to a ruler 25. A rod 26 is pivoted at opposite ends'to slide 6 and to the lower end of ruler 24, while an arm 27 is pivotally connected at opposite ends to the slide 5 and the lower end of ruler 25. A strip 28 is pivoted to the center of rod 27 and is connected at its ends to links 29, which are parallel and are pivoted to the arm 1. A link 30 is arranged parallel with the rod 27 and is pivoted to the rulers 23 and 25 and to strip 28. A strip 31 is pivoted to rod 21 and is parallel with arm 16, and this strip is connected to said arm by pivoted parallel links 32 and to the rulers 23 and 25 by a link 33, which is parallel with rod 21. A strip 34 is interposed between arm 16 and ruler 22 and is parallel oted links 35.

therewith, and this strip is pivoted to the rod 20 and is connected to arm 16 by parallel piv- A link 36 connects the strip 3 1 with the two rulers 22 and 24. A strip 37 is interposed between and parallel with the arm 2 and ruler 2 1 and is pivoted to the rod 26. Pivoted parallel links 38 connect the ends of strip 37 with arm 2, and a link 39, which is parallel with rod 26, connects said strip 3 with the two rulers 22 and 24.

When it is desired to produce a chimney-section having a base which is fourteen inches square, the three slides 5, 6, and 18 are adjusted within their respective grooves until their upper ends aline with the graduations designated by the numerals 14:. The slides are then locked in such position. This movement of the slides will cause the links and rods of the pattern to move the rulers from or toward each other and from or toward the arms 1, 2, and 16 until the distance between the rulers 22 and 23 is equal to fourteen inches and the distance between the ruler 24 and arm 2 and the ruler 25 and arm 1 is seven inches, respectively. The pattern is then laid upon the sheet of metal to be cut, and said metal is marked by drawing a line along the outer edge of each arm 1 and 2, along the inner or adjoining edges of the rulers, and along straight lines connecting the ends of the arms with the lower ends of the rulers. A lineis also drawn upon the metal by following the outline of the flexible rods 11. By cutting along the lines thus produced ablank is formed, such as shown in Fig. 2, and by making two of these blanks and joining them together a section of the desired shape is produced. The height of the section can be regulated by adjusting the strips 8 and 13 upon arms 1, 2, and 16, and the rods 11 can be adj usted longitudinally within the clampingblock 12, so that when the blank is cut it can be accurately fitted to a pipe of any predetermined diameter.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described the invention, what is claimed as new is 1. In a device of the character described, the combination with arms having slides adjustably mounted thereon; of rulers pivoted together and interposed between the arms, each ruler being parallel with one arm, and connecting devices interposed between the rulers and slides for adjusting said rulers in relation to each other and the arms.

2. In a device of the character described, the combination with arms having slides adjustably mounted thereon, and flexible adjustable connections between the arms at one end; of rulers pivoted together and interposed between the arms, each ruler being ,parallel with its adjoining arm, and connecting devices between the rulers and slides, whereby said rulers may be adjusted from or toward the arms.

3. In a device of the character described, the combination with graduated arms having slides adjustably mounted thereon, and adjustable flexible connections between the arms at one end; of rulers pivoted together and interposed between the arms, each ruler being parallel with its adjoining arm, a rod connecting each ruler with one of the slides, and linksconnecting the rulers and arms, whereby said rulers are maintained parallel with their respective arms.

4. In a device of the character described, the combination with grooved graduated arms having slides adj ustably mounted thereon, and flexible adjustable connections between the arms at one end; of rulers pivoted together and interposed between the arms, each ruler being parallel with the adjoining arm, rods pivoted at opposite ends to the slides and rulers, respectively, strips pivoted to the rods and parallel with the arms, and links connecting the strips with the arms and rulers.

5. The combination with graduated arms having slides adjustably mounted thereon, strips adjustably mounted upon the arms, and flexible connecting devices detachably and adjustably connected to the strips; of rulers pivoted together and interposed between the arms, each ruler being parallel with the adjoining arm, rods pivoted at opposite ends to the slides and rulers, respectively, strips pivoted to the rods and parallel with the adjoining arms, and links connecting said'strips with the rulers and arms.

In testimony whereof I afiix my signature in presence of two witnesses.
